云模型将概率论的随机性和模糊集合论的模糊性相融合，能很好地解决不确定性问题，基于此设计了一种二维液压弯辊云模型控制器，其控制策略不需要被控对象的数学模型，只需通过语言原子和云模型将人用语言定性表达的经验和逻辑判断转换到语言控制规则器中，就能实现板形实时在线控制。以某公司1220 mm液压弯辊板形控制系统为仿真对象进行仿真实验，结果表明，该控制器简易、快速、控制性能良好、鲁棒性强，较常规模糊控制具有更好的控制品质。

A cloud model combined the randomness of probability theory and fuzziness of fuzzy set theory,so the uncertain problems can be disposed better.This paper designed a two-dimensional cloud model controller of the hydraulic bending roll system,its control strategy needed no mathematical models of plant,the experience and logic decision qualitative expressed by linguistic value are trans-formed into the linguistic control rulers through linguistic atoms and cloud models,which can achieve flatness online control in real time.A hydraulic bending system of a company 1220 rolling mill was taken as the simulation obj ect.Simulation results show that the cloud controller is simple and rapid, has good control performance,strong robustness,and a better control quality than that of the normal fuzzy controller.
